Laadittu malli ei vaadi suurta laskentatehoa, joten se toimii nopeasti mikrotietokoneissa. Se on helposti sovellettavissa ja muokattavissa erilaisiin moottorin rakenneratkaisuihin.The aim of this stydy was to design a dynamic thermal model for axial-flux permanent magnet machine. The model can be used to design new cooling methods and constructions for this machine type.

The model is a thermal network whose components are mainly based on the evidence of existing literature. The power losses in each part of the machine were assumed to be known. The dynamic model can be used to simulate cyclic loading and transient action. The thermal network is divided into six sectors, thereby enabling analysis of an asymmetric cooling system and construction.

The model can be realised using either an APLAC® circuit simulator or Matlab® software. The heat transfer coefficients are defined from measured data. The effect of external ventilation is examined with measurements and modelling. The model also examines the effect of variation in parameters on thermal behaviour. Critical parameters are defined.

The constructed model requires no heavy computing and runs efficiently on a microcomputer. The model can be modified and applied to different machine constructions.
